I have configured a sshfs-mount in my fstab (with key-auth).
email@example.com:/ /mnt fuse defaults,allow_other,reconnect,_netdev 0 0
Works well as expected.
Last thing I need is a log on the client-side (I have no access to the server). I like to see if the connection is established and when it needs to reconnect.
I do not see anything in /var/log about it.
